Abstract: The invention relates to a pump installation which can be used in particular in liquid chromatography. In such pump installations a continuous volume flow of the eluent is also necessary on the intake side for the low pressure gradient formation. The object of the invention is to find a simple, economic and universally applicable solution which enables interference-free low pressure gradients to be obtained with single-piston pumps. This object is fulfilled according to the invention in that an additional displacement piston from the intake side of the pump is moved in a cylinder resulting in a continuous, even intake flow. During the intake pause this displacement piston draws in 50% of the set delivery quantity and in the intake phase of the working piston expels this quantity back out. <IMAGE>

Abstract: Excess current trip devices with immediate tripping contain at least one additional transmission member, to produce an immediate characteristic in the case of unequal loading of the phases, as well as bimetallic elements to detect the current in each phase. This exacerbates adjustment. The immediate characteristic is intended to be achieved in a more simple manner. …<??>A transformer-based current detection member (4, 7; 5, 8; 6, 9) is allocated to each phase. All the existing current detection members are connected in series to one another and to an electromechanical converter (10), which converter produces a time-delayed trip signal. The trip device can be added to normal switchgear with an excess current trip, as an additional module, or can be made effective, if needed, by the optional use of a switch (14). …<??>Switchgear for motor protection. …<IMAGE>…

IPC: G01P5/18
Filed: 1989-12-07
Abstract: A plurality of lasers each regulated to operate at a particular temperature, are supported by a manifold to direct coherent light into space. The regulation may be provided by producing pulses of a trickle current of a particular magnitude through the laser, measuring the voltage required to produce the trickle current and adjusting the characteristics of a thermoelectric member in accordance with the magnitude of such voltage to adjust the rate at which the thermoelectric member transfers heat from the laser. The lasers produce substantially parallel and thin beams of light in pairs. The light beams in each pair provide an optimum angle for the interception by such paired beams, of particles having individual trajectories in space. These particles scatter the light to a receiving lens system disposed within the manifold. The received light then passes through masks which restrict the collected light to a spatial pattern corresponding to the pattern of the light beams from the lasers. The received light beams passing through the masks are detected to produce signals indicative of the light in such beams. The manifold temperature may be regulated to maintain the optical characteristics of the lasers and the receiving system at a constant and optimum value. The regulation may be provided by disposing heat sleeves on the manifold periphery, preferably in both axial and annular directions, and disposing in each heat sleeve a porous wick and   a material convertible between liquid and gaseous forms. At positions above the regulated temperature, the liquid vaporizes and travels through the wick toward cooler spots where it vaporizes.

Abstract: The present invention relates to a process for piloting the distribution of the thread on the package under formation, in a collection unit for collecting synthetic threads, so as to prevent ribbness from forming during the continuous overlapping of different winding layers, so as to render easy and simple the subsequent technologic operations which the thread of the package has to be submitted to. 
     The present invention furthermore relates to an apparatus for the practical implementation of the process, which substantially consists in setting, instant by instant, the values of the operational parameters during the thread winding in such a way that the collection unit operates along descending portions of lines, with each being defined by a constant and non-integer "winding ratio" "K", and in containing said line portions inside a range bounded by a maximum threshold value and a minimum threshold value of the winding angle, with said maximum and minimum threshold values being symmetrical relatively to the value regarded as the optimum one, for the package under formation, and in furthermore   piloting the traverse cam in order to fix the dislocation of said descending line portions at a distance higher than, or at least equal to, a prefixed reference value, from a whatever line belonging to the group of "integer-K-value" lines, or of "exact-fraction-K-value" lines, which represent, as a whole, the orders of ribbness caused by the "mirror effects", regarded as detrimental to the winding which is taking place.

Even if a cylindrical member has a low rigidity, it can be grasped and transferred with little deformation of the cylindrical member. A tire building machine including such a transfer apparatus can improve the working efficiency and further achieve energy saving and improvement of formed accuracy.

Abstract: To improve the performance and life of a charging current-conducting commutating switch (36) in an inductor (30) storage-type electromagnetic launcher (10), the energy expended in propelling a mass (38) through a breech rail gun section at a high velocity is utilized to generate a current (I₁) in the breech section (12) rails (18,20) which flows through the commutating switch in opposition to the inductor charging current (I₀). The switch is opened in coordination with the movement of the mass through the launcher, with little or no arcing, when the current therethrough has been depressed to a minimal level to commutate inductor discharging current (I) into the rails (22,24) of a longitudinally aligned launch rail gun section (14) of the launcher to accelerate the mass therethrough to a high exit velocity.
